I've already done that. But the problem is that the kind of torsion I'm dealing with is not uniform along the axis of the hole. I want to find the torsional stiffness of the specimen with this specific type of torsion which has a gradient along the axis of the hole and I don't know the correct...
Hi thanks for your response.
I'm applying torsion in U2 direction in a cylindrical coordinate system which represents Theta and that's the direction that torsion should be applied! Do you think it should be in another direction?
I'm trying to model some sort of internal torsion by applying rotational displacement to one edge of a hole in the middle of a disk-shaped specimen. After getting the result, I see that only displaced nodes have non-zero displacement(equal to the applied displacement) values and all the other...
I will attach them in two different steps and there is no need for winzip or winrar. Here is the .cae file.http://files.engineering.com/getfile.aspx?folder=712a45f4-b037-43bf-a849-89571617e171&file=Model-10.cae
Attached you can find my files. Please have a look and let me know how I can improve it. Thanks a lot!http://files.engineering.com/getfile.aspx?folder=e16d2cad-d59e-4926-8866-42b820fcb400&file=ABAQUS_Model.rar
I checked my model again and I found the problem. Everything was ok, I just needed to remove the mandrel instance in the visualization module in order to see the correct stress distribution in the specimen.
But now I have another problem. I need to model slip between the mandrel and the specimen...
Hi Rob,
Thanks for your reply. I tried to remove aoverclosure by toggling on the "Adjust only to remove overclosure" in edit interaction dialog box. But it didn't work and I still get almost the same stress distribution in the specimen. Is it the right way to remove overclosure?
As you said...
Hi all,
I am modeling an insertion of a solid pin to a mandrel-specimen assembly. specimen has a central hole and mandrel is inside the hole. Pin will be pushed down in the hole which is drilled in the mandrel.
I've defined two pairs of contacts, pin-mandrel and mandrel-specimen. I've used both...
I'm applying the moment to DOF 6 (CM3)in moment type edit load dialog box. It's weird!
This is what is shows in the input file:
*Cload
_PickedSet22, 5, 100000.
Why is it 5?
Thank you for your instructions.
In my kinematic coupling constraint if I constraint all degrees of freedom, then it works very well, but when I just constrain UR3 (as you said), it doesn't work (it is for the case that I'm applying rotational displacement). On the other hand, to get my model...
This is the .jnl file of the model!http://files.engineering.com/getfile.aspx?folder=98658e4e-3088-4b4f-be7a-a2d892da4c8f&file=Solid_Cylinder_torsion.jnl
